At MEPS, they gave me the whole, "tell us everything because we'll find out anyway" speech. I told them everything. I got into a bunch of trouble in high school (pretty normal stuff, I just didn't get away with much) plus bad grades so my parents sent me to Charter mental hospital until the insurance ran out. They advertised expertise with handling my type of case. Anyway, there was talk of my being depressed, but no medication. Bad behavior (nothing worthy of keeping me out of the Navy) continued until boot camp during which the fear of God was put into me.
I talked to the recruiter, and he said to write a letter (and have my parents do the same) stating what happened and how we've tried to get the records. The doctor at meps sounded like I'd have trouble if I couldn't locate the records.
I think I did the right thing by being honest. It just looks like it will be a major hassle. But then, I only have myself to blame for that.
